Colt 10.3 GP

[sac]

Just wondering what the gp size is on the Colt 10.3 barrel? I've seen from .071 to .093

Thanks Scott

I saw that before, and thought that was for the cut down barrel from 14.5 to 10.3. But if it the same thank you.

I don't think that'd make a difference but I'm not 100% on that. I've understood it to be 0.070-0.071. I have a 10.3" Colt but I've never pulled the FSB to confirm.

Only a correctly made Colt 10.3" barrel or upper will have the Crane .071 gas port.

The way I read it a factory Colt 10.3 should be .071, thank you.
